To all whom it may-concern:

Be it knownthat I, JAMns' BOWDITOH, a sub]ect of theKmg of; Great Britain and Ireland, residing at 74 Maitland road, lsling- .ton, in the State of New South Wales, Commonwealth of Australia, have invented certain new and useful Improvements in Boat- Dropping Gears, of which the following is a specification. a i

This invention relates, to appliances installed inships. boats for the attachment thereto of lifting andlowering tackle and the release of such tackle as and when required.

And the object of the invention isto providegear whereby the tackle may as occasion requires be instantly released from each end of the boat simultaneously by one operation and the attachment of be effected at each end independently, so that the tackle having been attached at one end remains soattac'hed while the tackle is attached to the other end. In other words the gear is so constructed: and arranged that while release of the tackle. is effected by one operation, itsattachment requires two operations of which one remains effective while the other is performed.

Theinventi'on consists of gear installed in-each end of the boat as hereinafter described with reference to the accompanying drawings and more particularly specified in In the drawingsz Figure 1 is a broken perspective view of a boat fitted with gear according to this invention, the boat shown being double ended, but for distinction the left hand end in the drawing is hereinafter referred to as the stern while the right hand end is referred to as the bow.

Fig. 2 is a sectional perspective of the portion of the gear fitted in the stern, and

Fig. 3 a similar view of the portion of Fig. l is a longitudinal sectional elevation of part of the stern end of'the boat with the gear therein (in partly sectional elevation) engaging the tackle, and showing in dotted lines the release position of the parts, and I Z I Fig, 5-is a similar view of part of the bow end 0f the boat and its gear.

dependent means ready to receive the tackle link for attachment purposes i a Fig. 7 is a sectional plan on line 7.7 of Fig. 4, and i Fig. 8 a sectional 5, while Fig. 9 is sectional elevation on line 9.9 of Fig. 7. a

It is to be understood that I do not con line the application of my invention to a boat of the particular type illustrated, nor is my invention confined to the method illustrated and hereinafter described of mounting the gear in the boat as it is obvious that plan on line 8.8 of Fig.

.with different types of boats this may be respectively, and slots 13 and 14v are provided in said decking to permit the passage of tackle links 15 and 16 attached to the boat tackles 17 and 18 (see Figsa and 5.) V

In the stern of the boat the gear which is indicated generally in Fig. 1 by the, numeral 19 and is illustrated in clearer detail in Figs. 2, 4, 6, 7 and 9, comprises apost 2O stepped in the keel 21 and secured by a nut 22, said post passingthrough the bilge-board 23 and having an offset lug 24:, a slotted head 25, and terminating in an oppositely offset bracket or lug26 secured against the under side of the decking 12 bymeans of a bolt 27. To the lug 24 ispivoted 0n pin 28 the bell crank 29, the shorter and downwardly directed arm of which is pivotally connected to a: rod 30 running longitudinally of the boat above thebilge board under a cover plate 31- attached to the latter and connected to the'gear (hereinafter described) at the bow of the boat. The other arm of said bell crank 29 constitutes an operating lever 32 terminating in a footpedal 33. .Associated with said lever 32 is an auxiliary lever 34:

also pivoted on pin 28, but on the opposite side of lug 24 to the bell crank 29, its longer armfbeing terminally .rabbeted as at 85 to partly underlie the pedal33 of lever 32 (see Figs. (3, 7 and 9) while its shorter arrn'is pivotally connected to thelower endofa other end of which is pivoted at 39 invthe slotted headv 25 of the post so that said pawl also constitutes a link connecting the respective heads of the post and push rod.

A hook 40 to engage the tackle link 15' passed downwardly through slot 13 in decking 11 as in Fig. 4, is pivotally mounted 1n the slotted head of post 20 on pin'41 bifurcated headofpush-rod 36 nd provided positioned vertically below said slot 13, said hook having a tail 42 extending 1nto the with a notch 43 which is engaged by the corner 44 of pawl 38 to retain the hook point 45: in contact with the lug 26 and prevent escape of the tackle'link 15, as shown in full lines in Fig; 4. The levers 32 and 34 are pre vented from accidental operation by means of a guard chain 46 secured at one end of the post 20 and fitted at the other end with a shackle 47 the pin ofwhich is (when the hook '40 is closed and the levers register together as in Fig. 4) passed through the holes 48 and 49 in said levers respectively so that neither of them can be depressed until the pin is withdrawn.

Gear is provided in the bowof the boat and this is indicated generally in Fig. 1 by the numeral 50 and detailed more clearly in r Figs. 3,5and 8. i

The bow gear comprises a post 51-with 'lug' 52, slotted head 53, and top lug or bracket '54 which i attached to the decking V 12 by'bolt 55; also a push-rod 56'with bifurcated head 57, a pawl 58 pivoted thereto and 'to thehead of the post 51, and a hook 59 with tail 6O extendinginto the bifurcated head 57 of the push rod 56; The whole of these parts are constructed and relatively arranged in the same form and manner as the corresponding parts of the stern gear hereinbefore described.

To the lug 52. is pivoted on pin 61 a bellcrank 62 to the shorter anddownwardly directedarm of which is pivotally attached the connecting rod 30 extending from the stern arm of said bell crank 62 is pivotally connected to the lower'end of the push-rod. 56.

It will be seen that when the gears are closed asin Figs. 2 and 3, 4 and'5, the pawls 3S and 58 prevent theopening of the hooks '40 and '59 so that the tackle links 15 and 16 are held by their respective hooks for they lifting or lowering of the boat. When how-- f ever it is desired to drop the boat the levers 32and 34 are first released by withdrawing the pm of shackle 47 on guard chain 46and downward pressure is then applied. to pedal 33 of lever 32 thedepression ofwhich also depresses lever 34 which partly underlies said pedal 33. The depression of lever 32 partially rotates crank 29 whichbeing connectedby rod 30 to bell-crank 62 of the bow gear effects partial rotationof thelatter and raises the push rod 56. At the same time lever 34 by its depression raises push-rod 36. The result of the upward movement of pushrod 36 is to lift the pawl 38 from the notch 43 in the tail 42 of hook 40, and shoulder 64 contacts with said tail and by raising it opens the hook. Simultaneously push-rod 56 operates to open hook 59 in exactly the same manner so that tackle links 15 and 16 are freed at the same time.

To open the stern hook only, as may be required for attaching tackle to one end of the boat at one time, lever 34 is depressed hook 40.

Closure of the hook or hooks is effected by r the weight of the push-rod or push-rods, the

tail or tails of the hook or hooks being depressed by the pawl or pawls which engages or engage in the locking position before mentioned to hold the hook or hooks closed.

What I claim and desire to secure by Letters Patent is 1. Boat dropping gear comprising at each end of a boat, a fixed post, a hook pivoted to the head of said post to engage boat tackle, a pawl engaging said hook to maintain its point against a fixed abutment and means for releasing said pawl and allowing said hook to open; in combination with a lever, a rod connecting the pawl releasing means at each end and actuated by said lever, and means for releasing the pawl and thereby opening the hook at one end independently of the other.

2. Boat dropping gear comprising at each end of a boat, a fixed post, a hook pivoted to thehead of said post to engage boat tackle,

i a tailon said hook, a pawl engaging said tail lever pivoted to said post and pivotally connected at one end to said push-rod, a bellcrank pivoted to said post, one arm of said bell-crank constituting a lever partly overlying the first mentioned lever, the other arm of said bell-crank being attached to a connecting rod extending to the gear at the other end; also in'combination with, at the other end, a bell-crank pivoted to the post, one arm of said bell crank being pivotally attached-to and movable by said connecting rod, and its other arm pivotally attached to the push-rod.

3. Boat dropping gear comprising at one end of a boat, a fixed post having a slotted head terminating in a lug or bracket, a hook to engage boat tackle-pivoted in said slotted head and having a tail provided with a notch, a pawl pivoted at one end to said post and engaging the notch in said tail to maintain the hook point against said lug, a pushrod having a bifurcated head which embraces the extremity of said tail and in V which the other end of said pawl is pivoted, a lever to operate the'gear at one end only pivoted to said post and having one end pivotally attached to said push-rod, a bellcrank also pivoted to said post one arm of said bell-crank constituting an operating lever and terminating in-a pedal overlying part of the first mentioned lever; in combination with at the other end ofv the boat, a

(Maples of this patent may be obtained for fixed post with slotted head, a hook pivoted and having a notched tail, a pawl engaging said notched tail, and a push-rod pivotally connected to said pawl and embracing said operation of the tackle engaging hooks at each end on depression of the said pedal.
